title: Adhesion receptors and cytokine profiles in controlled tourniquet ischaemia in the upper extremity.
abstract: Adhesion mechanisms mediated by cytokines have been recognized to play a crucial role in ischaemia-reperfusion mechanisms. Although this phenomenon has been well investigated in organ transplantation, little data is available from upper extremity surgery. Profiles of adhesion molecules (CD11/CD18), key cytokines (TNF-alpha and IL-1), CD4+ and CD8+ lymphocytes, and polymorphonuclear neutrophils were investigated following controlled tourniquet ischaemia of the upper extremity for elective hand surgery. Data suggest that relatively short periods of ischaemia activate a mediator cascade and cell-cell interactions that may be associated with adverse pathopyhsiological effects on peripheral tissues after prolonged ischaemia.
